The 4 jumpers control the frequency range, while the 2 blue precision variable resistors control the frequency and duty cycle. It has 3 pins: positive, ground power supply and output pin, and the output pin is connected to a on board LED, which flashes within 1-100hz frequency range. As with all 555 chips, the operational power supply voltage are from 5-15 volt.         It's easy to use, convenient and practical for many of your electronic projects. I use these as a 12v DC to 120V AC wave generator for my backup power need and as PWM for my power LED dimmer circuit; It's really tiny and Neat, loving it!                                           Shipping: USPS First Class Mail 3-4 Day delivery estimation Return Policy: Return within 14 days to get a 100% full refund     Thank you for looking!
